Is DIY Off-Grid Advisor free to use?

Yes. The Scout plan is completely free — no credit card required. You can create builds, run the load calculator, use all the standalone tools, and join the community at no cost.

What off-grid systems does it support?

DIY Off-Grid Advisor supports vans, caravans, RVs, 4WDs, boats, cabins, sheds, and remote properties. It handles 12V, 24V, and 48V systems.

How does the Component Wizard work?

You enter your loads (appliances and usage hours), your location (for real sun hours), and your system type. The wizard then recommends the right battery bank, solar panels, MPPT controller, inverter, and DC-DC charger — all sized for your exact setup. It also generates a wiring diagram and PDF report.

Do I need electrical experience to use it?

No. The platform includes a full beginner-friendly knowledge base — Electrical 101, How-To guides, Troubleshooting, and a Glossary — so you can learn as you build. The tools are designed to guide you step by step.
